Step 2-2. Create New Document Type Shell DTD

In the base DITA distribution, find the file "concept.dtd" and copy it into the faq-question/dtd directory and rename it "faq-question.dtd" (in the sample materials this file is named faq-question-v1.dtd).

Edit this file as follows:

Try validating or opening the test document again. This time you should not get a "DTD not found" error but you should get "element type 'faq-question' not declared" sort of errors, indicating that it found the DTD but not the declarations for the FAQ-specific element types, which of course we haven't created yet. But we're making progress.
